Attachment member for insulation panel

1. An attachment member comprising:

a main portion having a forward edge and a rear edge;

a nailing hem extending transversely from the rear edge of the main portion in an upper direction, the nailing hem having openings through which a fastener can be inserted;

a forward wall extending from the forward edge of the main portion in the upper direction, wherein a height of the nailing hem is greater than a height of the forward wall;

a lip extending transversely from an upper edge of the forward wall in a forward direction away from the nailing hem;

a lower leg extending transversely from a central location of the main portion in a lower direction, the lower leg having opposing first and second ends, wherein the lower leg is connected to the main portion at the first end of the lower leg; and

a primary flange extending transversely from the lower leg, the primary flange located along the lower leg closer to the second end than the first end of the lower leg.

2. The attachment member of claim 1 , wherein the lower leg and the nailing hem are substantially parallel to each other and extend substantially perpendicularly from the main portion.

3. The attachment member of claim 1 , wherein a base of the nailing hem further comprises at least one spur extending transversely in the lower direction and in the forward direction.

4. The attachment member of claim 1 , further comprising a secondary flange extending transversely from the lower leg, wherein the primary flange is located along the lower leg further from the main portion than the secondary flange, and wherein the secondary flange is longer than the primary flange.

5. The attachment member of claim 4 , wherein at least one of the flanges has a stop surface and an angled surface that extends away from the main portion.

6. An insulation panel comprising:

a foam insulating layer comprising a front face, a rear face, a first end edge, and a second end edge that define a body of the foam insulating layer; and

an attachment member comprising:

a main portion having a forward edge and a rear edge;

a nailing hem extending transversely from the rear edge of the main portion in an upper direction; and

a lower leg extending transversely from the main portion in a lower direction at a point between the forward edge and the rear edge;

wherein the lower leg of the attachment member extends into the body of the foam insulating layer along the first end edge, the attachment member and the first end edge cooperating to be complementary in shape with the second end edge such that adjacent panels can engage each other.

7. The insulation panel of claim 6 , further comprising a veneer panel attached to the front face of the foam insulating layer, the veneer panel having a first end edge at the same end of the insulation panel as the first end edge of the foam insulating layer and a second end edge.

8. The insulation panel of claim 7 , wherein the veneer panel has a second wall that extends rearward along the second end edge of the foam insulating layer.

9. The insulation panel of claim 7 , wherein the first end edge of the veneer panel extends beyond the first end edge of the foam insulating layer.

10. The insulation panel of claim 9 , wherein the attachment member further comprises a forward wall extending transversely from the forward edge of the main portion in the upper direction, and the first end edge of the veneer panel extends to an upper edge of the forward wall.

11. The insulation panel of claim 10 , wherein the second end edge of the foam insulating layer comprises a groove complementary to the forward wall of the attachment member.

12. The insulation panel of claim 6 , wherein the foam insulating layer further comprises a recess in the rear face; and wherein the recess is shaped to accommodate the nailing hem.

13. The insulation panel of claim 6 , wherein the second end edge of the foam insulating layer is thicker than the first end edge of the foam insulating panel.

14. The attachment member of claim 6 , wherein a base of the nailing hem connecting to the main portion is thicker than an apex of the nailing hem.

15. An insulation panel comprising an attachment member, a foam insulating layer, and a veneer panel;

wherein the attachment member comprises:

a main portion having a forward edge and a rear edge;

a nailing hem extending transversely from the rear edge of the main portion in an upper direction;

a spur extending in a forward direction from a base of the nailing hem;

a forward wall extending transversely from the forward edge of the main portion in the upper direction;

a lip extending transversely from an upper edge of the forward wall in a forward direction;

a lower leg extending transversely from the main portion in a lower direction; and

a flange extending transversely from a lower end of the lower leg;

wherein the foam insulating layer comprises:

a front face, a rear face, a first end edge, and a second end edge that define a body of the foam insulating layer;

a recess in the rear face of the foam insulating layer that is shaped to accommodate the nailing hem of the attachment member;

wherein the front face is angled with respect to the rear face and the forward wall of the attachment member is angled to be parallel with the front face of the foam insulating layer; and

wherein a groove in the second end edge forms a front ridge and a rear ridge in the second end edge;

wherein the veneer panel comprises a front face, a rear face, a first end edge, a second end edge, and a lower wall extending rearwards from the second end edge, the lower wall running adjacent to the front ridge of the foam insulating layer and ending at the groove;

wherein the lower leg of the attachment member extends into the body of the foam insulating layer along the first end edge, the attachment member and the first end edge of the foam insulating layer cooperating to be complementary in shape with the second end edge of the foam insulating layer such that adjacent panels can engage each other; and

wherein the veneer panel is attached to the front face of the foam insulating layer.
